UTB

Sentry’s UTB system (Unitized Thru-Bore) is designed for ongoing field development at higher pressures. The Sentry UTB system utilizes mandrel hangers and pack-offs and can be run independently or together in a single trip, if needed. These hangers and pack-offs can be quickly tested after landing. Additionally, the UTB system incorporates standard off the shelf contingency casing hangers in the event that casing becomes stuck prior to reaching TD.

• The UTB is a through bore system, which allows the drilling rig to drill continuously, without removing the BOP until the drilling portion of the well is completed
• Mandrel hangers reduce the time required for landing casing and cementing
• Mandrel hanger pack-offs isolate the annuluses and allow for quick hydraulic testing of the annular seals after installation
• Integrates the use of standard tubing heads, tubing hangers and tubing head adapters
• Uses standardized running tools, bowl protectors and test plugs
